bbPress.org

Assuming it’s a static page cache that isn’t being invalidated? Seems odd the post and meta update wouldn’t flush the object and query cache automatically.

Any updates?

Just wondering about this.

Is W3TC “safe” to use with bbPress 2.0?

Regarding all the relative times (x minutes ago, etc), the best solution would probably be to put absolute times into all those places, along with some javascript to turn it into a friendly relative time at the client end.

As well as being cache-friendly, this solution would allow the possibility of locally updating, so if you switch to another tab in the browser and switch back a few hours later, the “1 minute ago” can change to “3 hours ago”.

I disabled the cache when I added bbPress to the site I am running, but desperately miss it (speedwise).

This kind of solution would allow me to reinstate the cache and everything would fly along nicely again!

@jjj

I didn’t understand from your reply do you want to add hooks that’ll purge cache made by caching plugins inside a core?

Problem with page cache and bbPress (outside relative times) is that when something new is posted, parent post type(s) isn’t cleared (for example, when you post a reply, topic’s and forum’s pages aren’t refreshed until cache expires).

In the meantime, I’ve gone for a) low cache time – 60 minutes, plenty enough to have good performance though, and b) disable cache for logged in users only. This seems to be a satisfactory solution to me.

I also found, under heavy load, that Super/Total cache didn’t help a great deal, while Quick Cache had a massive impact. YMMV though of course.

@johnconners – Any updates on your plugin? Page caching would be a HUGE help for large BBpress sites like mine.

Bated breath, etc

Could WP Super Cache tags do the job?

https://wordpress.org/extend/plugins/wp-super-cache/faq/

How do I make certain parts of the page stay dynamic?

There are 2 ways of doing this. You can use Javascript to draw the part of the page you want to keep dynamic. That’s what Google Adsense and many widgets from external sites do. Or you can use a WP Super Cache tag to do the job but you can’t use mod_rewrite mode caching. You have to switch to PHP or legacy caching.

There are a few ways to do this, you can have functions that stay dynamic or you can include other files on every page load. To execute PHP code on every page load you can use either the “dynamic-cached-content”, “mfunc”, or “mclude” tags. The “dynamic-cached-content” tag is easier to use but the other tags can still be used. Make sure you duplicate the PHP code when using these tags. The first code is executed when the page is cached, while the second chunk of code is executed when the cached page is served to the next visitor. To execute WordPress functions you must define $wp_super_cache_late_init in your config file.

dynamic-cached-content example

This code will include the file adverts.php and will execute the functions “print_sidebar_ad()” and “do_more_stuff()”. Make sure there’s no space before or after the PHP tags.

<!--dynamic-cached-content--><?php

include_once( ABSPATH . '/scripts/adverts.php' );

print_sidebar_ad();

do_more_stuff();

?><!--

include_once( ABSPATH . '/scripts/adverts.php' );

print_sidebar_ad();

do_more_stuff();

--><!--/dynamic-cached-content-->

mfunc example

To execute the function “function_name()”:

<!--mfunc function_name( 'parameter', 'another_parameter' ) -->

<?php function_name( 'parameter', 'another_parameter' ) ?>

<!--/mfunc-->

mclude example

To include another file:

<!--mclude file.php-->

<?php include_once( ABSPATH . 'file.php' ); ?>

<!--/mclude-->

That will include file.php under the ABSPATH directory, which is the same as where your wp-config.php file is located.

Example:

<!--mfunc date( 'Y-m-d H:i:s' ) -->

<?php date( 'Y-m-d H:i:s' ) ?>

<!--/mfunc-->

Likely unknown issues surfacing, or bbPress becoming more complex over time and W3TC interoperability not being specifically tested.

Thanks for sharing @will-brownsberger . So it’s been 3 weeks, how are you doing? 🙂 There’s also a mention of a fix in that thread you linked to, but I’m not sure if it’s been applied yet.

We’re on a constant lookout for bbPress-compatible plugins to use on jmonkeyengine.org. It could really save us from a very costly hardware/hosting investment.

Just installed W3 total cache yesterday and it seemed to work. When I tried logging in through a sidebar widget it did not work. Disabled page caching and it works again.

So I guess there must be an exclude setting for the forum area that could make it work. Will try this this evening.
